ECM Fault?

[Akselrud, Boris]

That's very interesting. Where do I get the tiny tubing and what do I use
for restrictions?


At some point I inserted a receiver chamber in the MAP line to see what it
does. Unfortunately the vacuum squashed the bottle I found.

Running a restrictor just screws things up (long term),
(try starting at .018" for both and 1/8+ vac line), if your running 1/8"
line that might be your problem, need to use the tiny stuff gm uses for best
results and keep line short.  Need to run two restrictions, and a dampening
chamber between them
but then transistions are a bitc- to get right.
